AUTOMATIC KNIFE. ATTACHMENT FOR WET-MACHINES.

Application filed March 21, 1919.

To all whom it mo" concern:

Be it known that I, EUGENE MARIUS Benn, a citizen of Switzerland, residing at 2256 St. Andre street, in the city of Mona treal, in the Province of Quebec, in the Dominion of Canada, have invented certain new and useful Improvements in Automatic Knife Attachments for l Vet-Machines; and I do hereby declare that the following is a full, clear, and exact description of the same.

The present invention relates to improvements in a knife attachment to press rolls of wet machines and the main object of the invention is to provide a pulp cutting knife that is automatically operated by the revolving press roll.

A further object of the invention is to devise suitable means of adjusting the knife.

The invention will be better understood with the aid of the accompanying drawings in which:

Figure l is a side elevation of the press roll of a wet machine having adapted thereon the knife attachment.

F ig. 2 is an end view of Fig. 1, looking in the direction of the arrow.

Fig. 3 is a cross section on line aa of Fig. 1.

Like numerals of reference indicate corresponding parts in each figure.

In the drawings, 1 is the press roll of a wet machine suitably supported and journaled in the standards or uprights 2 at each end thereof. At one end of said roll 1 18 secured a collar 3. Above said press roll is a parallel shaft or bar at which projects through holes 5 in said standards 2, and 6 is a channel bar secured below said shaft by the bolts 7 and in vertical relation thereto. Adjacent the lower edge of said channel bar 6 is provided a plurality of holes 8 and 9 is a plate having a lower cutting edge 10 and adjacent its upper edge a plurality of slots 11 adapted to register with the holes 8 and 12 are bolts adapted to rigidly secure said plate 9 to said channel bar 6, and whereby it may be adjusted to any convenient height.

On said shaft 4, in alinement with said Specification of Letters Patent.

Patented Nov. 18, 1919.

Serial No. 284,182.

collar 3 is an adjustable member 13 having a lower forked portion 14 in which is rotatably secured a cam 15 adapted to contact with said collar 3.

The operation of the cutting attachment will easily be understood. The press roll 1 when in rotation will naturally rotate the cam 15 which in turn will cause a lifting and lowering action to the plate 9. The plate 9 will at equal intervals fall against the pulp which is around the roll and cut it.

l/Vhat I claim as my invention is:

1. A device of the character described in combination with a cylindrical rotating member, of a shaft movably secured above and parallel to said cylindrical member, a cutting element adjustably secured to said shaft, a bracket secured at one end of said shaft and a cam rotatably mounted in said bracket and adapted to contact with said rotating cylindrical member substantially as described.

2. A device of the character described in combination with a rotating cylindrical member supported and journaled on suitable uprights, of a shaft suitably ournaled above said cylindrical member in said uprights, a member downwardly projecting from said shaft provided adjacent its lower edge with a plurality of holes, a cutting element consisting of a plate having a lower cutting edge and adjacent its upper edge a plurality of vertical slots, bolts adapted to project through said holes and slots in said member and said cutting element whereby said cutting element may be suitably adjusted, a bracket secured at one end of said shaft and a cam rotatably mounted on said bracket and adapted to contact with said cylindrical member whereby said cutting element will be operated substantially as de scribed.

Signed at Montreal, Quebec, Canada, this 24th day of February, 1919.

EUGENE MARIUS BENE.
